Get records

get_records(
  ids,
  prefix = "oai_dc",
  url = "http://api.gbif.org/v1/oai-pmh/registry",
  as = "parsed",
  ...
)

Arguments

ids

The OAI-PMH identifier for the record. One or more. Required.

prefix

specifies the metadata format that the records will be returned in. Default: oai_dc

url

(character) OAI-PMH base url. Defaults to the URL for arXiv's OAI-PMH server (http://export.arxiv.org/oai2) or GBIF's OAI-PMH server (http://api.gbif.org/v1/oai-pmh/registry)

as

(character) What to return. One of "parsed" (default), or "raw" (raw text)

...

Curl options passed on to GET

Value

a named list of data.frame's, or lists, or raw text

Details

There are some finite set of results based on the OAI prefix. We will provide parsers as we have time, and as users express interest. For prefix types we have parsers for we return a list of data.frame's, for each identifier, one data.frame for the header bits of data, and one data.frame for the metadata bits of data.

For prefixes we don't have parsers for, we fall back to returning raw XML, so you can at least parse the XML yourself.

Because some XML nodes are duplicated, we join values together of duplicated node names, separated by a semicolon (;) with no spaces. You can seprarate them yourself easily.
